LOOSE-LEAF LEDS-ER.

Application filed September 19, 1922.

To @ZZ y107mm it muy concern Be it known that I, JOHN SCHADE, a citizen of the United States, residing at the city of Holyoke, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Loose- Lcaf Ledge-rs; and I do declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

T his invention relates to certain new and useful improvements in loose lealedgers, and the primaryobject thereof is to provide a ledger wherein the angle sections carrying the side cover members constitute the back, thereby dispensing with the necessity of providing a special back for the ledger, and one wherein the central pivot rod about which the yangle sections and side cover members are hinged or swing, is employed to control or release the mea-ns which locks or latches the sections together.

The invention still further aims to provide a ledger construction which when open enables the leaves to lie more nearly iiat or horizontal and which also enables kthe side cover members to be made on a standard machine.

Still turther, the invention aims to improve the securement ot the prongs and to provide a locking mechanism which is eilicient and devoid ot parts subject to becoming loose or rendered inoperative.

rl`he invention has still Jfurther and other objects which will be later set forth and manifested in the course ot the following description.

In the drawings Figure 1, is an end elevation of the invention; j

Figure 2, is a section on line 2-2 of Figure 1;

Figure 3, is a section on line 3-3 of Figure 2;

Figure 4, is a top plan'view ot the ledger in open posit-ion;

Figure 5, is a section on line -5 of Figure l;

Figure 6, is a detail sectional view ot a releasing means, an

form of stop for limiting the movement of the operating rod.

ln proceeding in accordance with the present invention, a pair of angular metal back sections 1 and 2 are employed to which the side cover members 3 ands. are suitably secured, the adjacent sides of the sections being formed with hinge knuckles 5 that receive the combined pintle-forming and lock releasing rod 6. Rod 6 is equipped with a radially extending linger piece 7 by means ot which the rod is operated. Riveted to the angular back sections are the substantially L-shaped latching members 8 and 9, member 8 being resilient while member 9 is rigid. he resilient member 8 has its free or eii'ective end turned over as indicated at 10 and then extended outwardly to form a stop 11, located at about the center of the end 10. The turned over end 10 forms a resilient latch member which engages with a latch 12 which is rigid and extends outwardly from the Jfree end of the rigid memseen that the latch snap over the latch 12 together.

For the purpose of releasing the latch 11 from engagement with the latch 12, a sleeve 13 is rigidly secured to the rod 6 and carries a releasing member 14, the free end of the latter engaging the resilient latch 10 to compress or force the latch out of engagement with the latch 12, thereby releasing the angle sections and permitting opening of the ledger. The latch 12 and member 9 are biturcated at 15, to allow the releasing member 1a to pass and thereby permit full opening of the ledger.

The stop 11 acts to engage the releasing member 12 so as to prevent overthrowing of the latter with respect to the resilient latch member 10. This stop 11 is not necessary although it may be used and its use is preferable in order to prevent overthrowing of the releasing member by careless or indifferent users.

As depicted in Figure 6, a modified form ot releasing means is disclosed, and in which in lieu of the sleeve 13, a pin may be employed which may be riveted in an opening provided therefor in the rod 6', the latter Cil Lit)

corresponding to the rod 6 in the other views of the drawing. With this modified structure, the adjacent hinge knuckle is formed with a transverse slot 21, through which the pin projects.

As a modified form of stop, in cases where the use ci a stop is desired, the hinge knuckle 5 adjacent to linger piece 7 mayu be cut away on its outer end as indicated at 22 in Figure 7 so as to engage the finger piece and thereby limit turning movement of the rod 6 accordingly. The knuckle, linger piece and rod correspond tothe similar parts in the remaining figures.

For the purpose of enabling the leaves to lie more nearly flat or horizont-al, it will be seen that the outer ends of the angle sections l and 2 are bent outwardly at 25, or relatively diverge, which greatly contributes toward at disposition of the leaves when the ledger is open. As depicted in Figure 5 of the drawing since should the ends work up, the free edges thereof cannot catch in the leaves the prongs 26 are provided with shoulders 27 which are s-Waged thereon, following which the prongs are riveted as shown at 28 to the angle sections. l and 2.

From the foregoing it will be seen that the back of the ledger isprovided by the adjacent parts or sides of the angle sections l `and 2 and that the latter not only carry the latching means 8 and 9, but in addition the rod 6 which acts in a dual capacity, namely to aiord a hinge pintle for the knuckles 5 of the angle sections and also means for supporting and operating the releasing member 11i or 2O of the latching device, It will be further seen, that the releasing member is so mounted on the rod 6 or 6', so as to cooperate with the hinge knuckles to prevent any lengthwise movement of the rod with respect to the structure.

What is claimed is: Y

l. In a loose leaf ledger, angular back sections, a rod pivotally connecting' the sections, latch members secured to the back sections and'being disposed to substantially aline when the ledger is in. closed position, one of the latch members having a substai.- tially U-shaped free end formed with a lateral stop and the other latch member having a catch formed to engage with the stop, the second named latch member. having a slot located adjacent to said rod, and a releasing member rigid on the rod and movable in the slot to engage said U-shaped end of the latch member to disengage same from the catch and having its movement limited by engagement with said stop.

2. In a loose leaf ledger, angular back sections, a Vrod pivotally connecting the sections, latch members secured to the back secsite to the rod and at a and means carried by the tions and being disposed to substantially aline when the ledger is in closed position one of the latch members having at its free end turned over and the other latch inem ber having a catch' form to engage the extremity of said turned over free end, the second named latch member having a slot, and a releasing member on the rod movable in the slot and cngageable with the turned over end oit the iirst named latch member.

3. In a loose leaf ledoer, angular bach sections, a rod pivotally connecting the sections, latch members carried by the sections and having intercngaged parts, and releas ing means carried by the rod and having a free part to Wipingly engage one of the latch members to eilect disengagement oit the interengaged parts of the members.

4. In a loose leaf ledger, angular back sections, a rod pivotally connected to the sections along the edge portions of o-ne side of the sections, cooperating latch members secured to the other sides ot the sections and disposed to lio substantially parallel to the first named sides of the sections when the parts are in ledger-closed position, and means carried by the rod to release the members from latched position.

5. In a loose leafledger, angular back sections, a rod pivotally connecting the sections, cooperating latch members carried by the sections and disposed to lie ina substantially straight line extending across the rod and having intereiigaged parts disposed opposite adjacent to the rod when the ledger is in closed position, and releasing means to disengage the latch members carried by the rod.

6. In a loose leaf ledger, angular back sections, a rod pivotally connecting the sections, cooperating latch members carried by the sections and disposed to lie in a substantially straight line extending across the rod and having interengaged parts disposed Vopposite adjacent to the rod when the ledger -is in closed position, and releasing means carried by the rod and l having a free part Wipingly engaged with one of the latch members to disengage the latter.

7. In a loose leaf ledger, angular back sections, a rod pivotally connecting the sections, latch members having parts formed to automatically snap into engagement with each other at a point substantially oppopoint at approximately the center of the lengths of the rod, rod to engage the latch members and release same.

In testimony whereof I affix my signature hereto.
